Could someone point me to Brand's electronic money protocol? I have heard of it and would like to learn more. If it is a discussable topic then please someone try to convince me that it is better than Chaum's or Chaum's-plus-anonymity-both-ways, or some other candidate for E-Money Protocol Which Has Official Cypherpunk Blessing.

<URL:http://ganges.cs.tcd.ie/mepeirce/Project/Mlists/brands.html> has a good collection of earlier discussions on Brands' cash, as well as pointers to Brands' work itself. Brands' home page, <URL:http://www.cwi.nl/~brands> has a long list of advantages which his system has over Chaum's original cash proposals, mostly technical in terms of efficiency and provability. Brands' and Chaum's systems have similar anonymity properties so I don't see much to choose between them on political grounds. Brands tends to work in the context of off-line systems with "observer" chips which prevent double spending. But his protocols can be used in other payment environments as well. Hal Finney
